V4 Claims.- (orina-9 7)Y Y g clined-'deflector ledge I1, said ledge separating This inventionrrelates to the general art of coin controlled vending machines-and more especially to coin controlling devices by which an automatic selection of the meansfor actuating the coin controlled mechanismis effected, legitimate coins being accepted, andrspurious substitutes being rejected. One ofi the commonest fraudulent coin substitutes used in. these machines is a Washer of substantially the thickness and diameter of the legitimate coin. Most of these washers are a standard product and easily obtainable on the market, and therefore are extensively usedV in eiorts to cheat coin controlled vending machines. v

Themain object of this invention is to provide a very'simple, inexpensive and efficient coin controlling device thatmay be relied onto pass proper and legitimate coins of the size for which the machine isintended and to reject Washers and Vall similar articles that are formed with a central hole. A

An illustrative embodiment of the invention is illustrated in the accompanying drawing, in which:y Y y l Fig. 1 is a iront elevation of the upper portion of a coin chute having myimproved coin selectlngdevice applied thereto. l

Figs. 2, 3 and 4 are fragmentary vertical sections all taken on the vline 2-2 of Fig. 1 and showingthe relative positions of the parts dur-V ing the progress of .a washer. therethrough. v Y

Fig. 5 is a view also on the line 2 2. of Fig. 1 showing the parts in the position corresponding to Fig. 3, but illustrating the lactvionvof, the ,Selecf tor device on a legitimate coin.

u Fig. 6 is a transverse section takenj on the line 6,-6ofFig.1.

VvFig-'l is an elevationsimilar to Fig. 1, viewed from the opposite side of the latter. i Figs. 8` and 9 areiperspective details ofthe two members of an oscillating selector device, through the action of ,which legitimate coins arepassed to the coin receptacle and washers or `similar spurious tokens are thrown out.A Referring to the drawing, I Il and II designate as entireties two wall members that are `connected as by screws I 2 and are suitably spaced to form between them a coin chute I3.l Asshown in Fig. 1, the upper end of the Wall I 0 is cut away to'provide an open-L ing I 'I of suitable size for the vinsertion sidewise intoA the chute ofthe c oiri. f' In the wall III, a short distance below the coin deposit opening I4 are upper and lower openings I5 and I6 respectively. i Between 'these' openings and extending across the coin chute I3is an inf'- Y the openings I5 and1I6. Attached to the outer face of thewall' I0 as by screws I8 are a pair of Z-bars I 9,^theadja cent inner portions of which overhang theside portions ofv the openings I 5 and I6 and form, between them a channel 20 that is,v

laterallyiadjacent to the chute I3 and intowhich channel the tokens, whether a legitimate coin or,l a washer, are directed Vfrom the lchute-I3 by the; deflector ledge Il, as is clearly shown in; Fig. 2.I I-f the article deposited be a yspurious annular to,- ken, such as a washer, itl will fall through the channel.20, and,drop onto the floor of themachine. If the deposited token be ar` legitimate coin of the size intended to be used on the machine, it` will be pushed from the channel 2U back into the coin chute I3, will Vdrop on an inclined. ledge 2l conveniently formed integral with the wallfl land extending-throughV a slot 22, in the wall` I0, and will roll down said ledgeginto a chute 23. L Y' 1, Coming now to a descriptionfof the selector device by which legitimate coins areaccepted and washers yandthe like are rejected, mounted on one of the Z-bars I 9l is an angle bracket-2Min which ismounteda stud 25.. Pivotally mounted o n this stud are the two cooperating members lof the coinv selector shown in isolateddetail in Figs. 8 and 9. Bothofthese members are flat metal members disposed side by side, and one of them identified by 26 has a relativelylonger iinger 21, a notch 28 cut in its vertical edge above.` the nger 2,1, a counter Aweighted tail piece 29, and a stop lug 30 on its upper edge. k'l'he Vothenmember identiedas a whole .by 3l has a relatively' short iinger 32, a tail piece 33, and alateral lugl34 on the lower edge of the finger 32. When the parts are'assembled on the stud 25, the lugv34 lies'in and, in the operation of the-device, vplaysbetween the top and bottom edges of, the notch 28.

As shown in Figs.Y 2 to `5 inclusive, the longer iinger 21 is long enough to extend acrossfthe channel 20 andthrough the lower opening I6 into theV chute I3. `The shorter. finger 32is long enough to project into the channel20, but does not extend in any position thereofY in to the chute I3. .The counter weighted tail piece 29 normally m' a.i ntains the parts lin the -position shown Vin Fig; 2.

' If c a washer, identified by isinserted into the coin chute, it is handled by the selector Vdevice` in the manner-progressively illustrated in Figs. 2,l 3 and 4; It'is iirst deiiected by the ledge I'I from the lcoin chute I3 Vinto the channel 20, Its lower edge vstrikes the'base ofthe finger 21 PATENT *OFFICE to,S

isV rocked with `the' member 26. the washer falls down the channel, theend of the linger 32 enters the hole ofthe washer` .(Fig.1 K' 3) it does'not'interf'ere.'with'the straight falling movement of thefwa'sher, so that' the latter drops out of the lowerend of. the channel,` and in so doing its upper portionwipes across'VV the upper Y corner of the finger 32 as shown ini/FlgV-thus the mid'positionshown inFigs; 3'and5 ixrvvhich.`
